iSCSI: Failed to connect to LUN : iscsi_service failed

[mbartho]

We are working on setting up a ZFS to iSCSI share on Freenas. We have the SSH keys setup up, installed the patches, and set up the zfs to iscsi share in proxmox. It appears to be connected is showing as available and reports the correct available storage. However, when we attempt to move the hard drive of a VM from the current location to the new storage, we receive the following error:

Can anyone provide insight into the cause of the problem and hopefully a resolution? We have looked all over and have not been able to find a solution.

Hi,

Just fixed this with commit 0b760eefc3ae8787e4d83235ca20e2ae886cf166.

In TrueNAS-Scale the slashes (/) needed to be converted to dashes (-) which it was doing but only the first slash (/). Adding the 'g' parameters to the regex substitution fixed this.
You may need to 'edit' your extents on the TrueNAS to fix this or some other way to make it look like Jarhead-Virtual:201-vm-201-disk-0.raw.

Hi, have some problem, I can't understand your comment on how to correct it, if you can tell me with more details, thanks

command
/usr/bin/qemu-img convert -p -n -f raw --target-image-opts /mnt/pve/NAS00.DISK/images/167/vm-167-disk-0.raw 'file.driver=iscsi,file.transport=tcp,file.initiator-name=iqn.1993-08.org.debian:01:a0fd17a7dc2f,file.portal=30.30.30.30,file.target=iqn.iscsi.rak.00.nas.urbs:zfs,file.lun=1,driver=raw'

error

I solved my problem, I had the portal configured wrong and I needed to execute the commands

"7. Once you have added the ZFS over iSCSI space within Proxmox GUI, you must log in to the iSCSI target from each node with the following commands:
iscsiadm --mode discovery --op update --type sendtargets --portal [Portal IP]
iscsiadm -m node -T [BaseName:TargetName] -p [Portal IP] -l
8. Verify the iSCSI connection with the following commands:
iscsiadm -m node
iscsiadm -m session"

from the guide, I am attaching the guide I found again, so that it may be of use to someone else, with these guides I was able to configure ZFS over ISCSI
